<p><P>PROBLEM TO BE SOLVED: To provide a two-in-one horizontal tier type inverter transformer which can drive two straight tubes in phase to illuminate and has compact constitution such that area of installation on a substrate is small. <P>SOLUTION: A magnetic core 4 includes two I type cores 41 and 42 and an E type core 43, which has a first core 44 inserted into a primary winding 1, a second core 45 inserted into a first secondary winding 2, a third core 46 inserted into a second secondary windings 3, and a one-end side connection core 47 which connects one-end side ends of the first to third core 44 and 46 to one another. The two I type cores 41 and 42 are disposed so that ends 41a and 42a thereof are disposed to face each other with an axis C<SB>1</SB>interposed therebetween at a predetermined interval and also both in contact with one end of the first core 45, and two magnetic paths M<SB>1</SB>and M<SB>2</SB>are separated. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
